Intel Dual-Band Wireless N / Bluetooth 4.0 Adapter
Supports WiFi on the 2.4 and 5 GHz frequency ranges. A great way to cheaply add 5GHz support to a laptop that doesn't already have it. This chip fits in any half-height or full-height PCI Express Mini socket.
I have three available, in their original protective packaging.
